2020-07-21xfrm: Fix crash when the hold queue is used.Steffen Klassert
The commits "xfrm: Move dst->path into struct xfrm_dst" and "net: Create and use new helper xfrm_dst_child()." changed xfrm bundle handling under the assumption that xdst->path and dst->child are not a NULL pointer only if dst->xfrm is not a NULL pointer. That is true with one exception. If the xfrm hold queue is used to wait until a SA is installed by the key manager, we create a dummy bundle without a valid dst->xfrm pointer. The current xfrm bundle handling crashes in that case. Fix this by extending the NULL check of dst->xfrm with a test of the DST_XFRM_QUEUE flag.

2020-07-20riscv: kasan: use local_tlb_flush_all() to avoid uninitialized __sbi_rfenceVincent Chen
It fails to boot the v5.8-rc4 kernel with CONFIG_KASAN because kasan_init and kasan_early_init use uninitialized __sbi_rfence as executing the tlb_flush_all(). Actually, at this moment, only the CPU which is responsible for the system initialization enables the MMU. Other CPUs are parking at the .Lsecondary_start. Hence the tlb_flush_all() is able to be replaced by local_tlb_flush_all() to avoid using uninitialized __sbi_rfence.

2020-07-20tipc: allow to build NACK message in link timeout functionTung Nguyen
Commit 02288248b051 ("tipc: eliminate gap indicator from ACK messages") eliminated sending of the 'gap' indicator in regular ACK messages and only allowed to build NACK message with enabled probe/probe_reply. However, necessary correction for building NACK message was missed in tipc_link_timeout() function. This leads to significant delay and link reset (due to retransmission failure) in lossy environment. This commit fixes it by setting the 'probe' flag to 'true' when the receive deferred queue is not empty. As a result, NACK message will be built to send back to another peer.

2020-07-20net/smc: fix dmb buffer shortageKarsten Graul
There is a current limit of 1920 registered dmb buffers per ISM device for smc-d. One link group can contain 255 connections, each connection is using one dmb buffer. When the connection is closed then the registered buffer is held in a queue and is reused by the next connection. When a link group is 'full' then another link group is created and uses an own buffer pool. The link groups are added to a list using list_add() which puts a new link group to the first position in the list. In the situation that many connections are opened (>1920) and a few of them stay open while others are closed quickly we end up with at least 8 link groups. For a new connection a matching link group is looked up, iterating over the list of link groups. The trailing 7 link groups all have registered dmb buffers which could be reused, while the first link group has only a few dmb buffers and then hit the 1920 limit. Because the first link group is not full (255 connection limit not reached) it is chosen and finally the connection falls back to TCP because there is no dmb buffer available in this link group. There are multiple ways to fix that: using list_add_tail() allows to scan older link groups first for free buffers which ensures that buffers are reused first. This fixes the problem for smc-r link groups as well. For smc-d there is an even better way to address this problem because smc-d does not have the 255 connections per link group limit. So fix the problem for smc-d by allowing large link groups.

2020-07-20rxrpc: Fix sendmsg() returning EPIPE due to recvmsg() returning ENODATADavid Howells
rxrpc_sendmsg() returns EPIPE if there's an outstanding error, such as if rxrpc_recvmsg() indicating ENODATA if there's nothing for it to read. Change rxrpc_recvmsg() to return EAGAIN instead if there's nothing to read as this particular error doesn't get stored in ->sk_err by the networking core. Also change rxrpc_sendmsg() so that it doesn't fail with delayed receive errors (there's no way for it to report which call, if any, the error was caused by).

2020-07-20fscrypt: rename FS_KEY_DERIVATION_NONCE_SIZEEric Biggers
The name "FS_KEY_DERIVATION_NONCE_SIZE" is a bit outdated since due to the addition of FSCRYPT_POLICY_FLAG_DIRECT_KEY, the file nonce may now be used as a tweak instead of for key derivation. Also, we're now prefixing the fscrypt constants with "FSCRYPT_" instead of "FS_". Therefore, rename this constant to FSCRYPT_FILE_NONCE_SIZE.

2020-07-20fscrypt: add comments that describe the HKDF info stringsEric Biggers
Each HKDF context byte is associated with a specific format of the remaining part of the application-specific info string. Add comments so that it's easier to keep track of what these all are.
